Product Family:  Software

Product Line:  Aldec

Problem Title:
Foundation Simulator: End of time error


Problem Description:
Keywords: End of time, Foundation, simulator, precision

Urgency: Standard

General Description:

Aldec uses a 32 bit integer to track the number of clock
periods.  This results in approximately four billion clock
periods that can be tracked.  When this integer overflows, an
'End of time error' is reported.


Solution 1:

This error can be fixed by changing the 'Simulation Precision'.
This can be done with the following steps:

* In the Logic Simulator, select Options->Preferences.
* In the tab section 'Simulation', change the  'Simulation
  Precision' to a larger number.  Click on 'OK'.

The design can now be simulated.
